我找不到servlet错误。我使用WIldFly。我的目录结构如下所示:
root - > app,converter.html,src
app - > WEB-INF
WEB-INF - > classes,lib,web.xml
src - > servlet.java
我已经查看了一段时间,无法确定问题所在。我认为我在web.xml中正确映射了映射,并且表单操作似乎也被发送到.html文件中的正确位置。
Servlet类:
import java.io.IOException;
import java.util.*;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class servlet extends HttpServlet{
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException{
String username = request.getParameter("username");
String email = request.getParameter("email");
response.getWriter().println("<html>");
response.getWriter().println("<head>");
response.getWriter().println("<title>Title</title>");
response.getWriter().println("</head>");
response.getWriter().println("<body>");
response.getWriter().println("Convert. ");
response.getWriter().println("</body>");
response.getWriter().println("</html>");
}
}
的web.xml
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<servlet>
<servlet-name>servlet</servlet-name>
<servlet-class>servlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>servlet</servlet-name>
<url-pattern>/servlet</url-pattern>
</servlet-mapping>
</web-app>
converter.html
<!DOCTYPE html>
<html>
<head>
<title> Test form </title>
</head>
<body>
<form action="http://localhost:8080/root/src/servlet" method="get">
Name: <input type="text" name="username"><br>
Email: <input type="text" name="email"><br>
<input type="submit" value="Submit">
